Brightness bug with dual display mode

So I moved to Lucid. It was a pain to make fglrx work after upgrade. It somehow messed up with nvidia drivers and while Xorg was loading fglrx it was loading glx and dri extensions fron nvidia package. I fixed symlinks and installed fglrx 10.7.
Brighness control works ok while I’m on laptop without external display. But when I’m in dual display mode brightness control works only from power managmer. While using fn keys brightness popup doesn’t move.
Well, it’s time to fix a new bug.
